The Demon's Lexicon

Nick and Alan Ryves are demonologists and fighters, the only ones who know the truth about the amulet their mother once held — and the only ones who can protect Mae and Jamie, two teenagers who have stumbled into the same dangerous world. Hunted by the sorcerer Black Arthur and his Obsidian Circle, the Ryves brothers must navigate the Goblin Market, a hidden sanctuary for those touched by the supernatural, while unraveling the dark history of their own family. As the truth about the amulet and the fate of the Crawford siblings slowly comes to light, the line between protector and prey begins to blur.
